Title: A machine for moulding glass bottle stoppers
IPC: C03B11/02
Filed: 1920-05-15
Abstract: 164,224. Nelson, Ltd., W., and Easton, W. B. May 15, 1920. Pressing.-Relates to a rotary table machine for moulding glass stoppers having disc-shaped heads and taper shanks. An annular table d carries a series of moulds e each of which is provided with multiple holes for simultaneously forming the shanks of a number of stoppers, the heads being formed in a corresponding stationary mould j. The table is given a step-by-step motion through the action of a ratchet wheel and pawl g<1>, which is actuated through links by a cam on a disc f<4>, the disc f<4> being geared with the main driving shaft a. The table is supported by spring-mounted rolls d<1> so that it is normally slightly above the mould j. A presser frame k connected by links k<2>, k<3> to pillars k<1> is suspended above the mould y. When one of the moulds e is in position above the mould y, glass is supplied to it and is pressed into the coacting moulds by the descent of a plunger o<1> carried by a cross-head n sliding on pillars m. Before the plunger o<1> reaches its operative position, smaller plungers o<3> press the frame k on to the mould e which is thus held in position. During the moulding the table d is depressed owing to the spring rolls yielding, but rises again on the ascent of the plungers. The frame k is lifted by rods o<4> with hooked ends which are operated by fixed pieces p. When the table rises it lifts the stoppers out of the mould j and carries them round to the position shown at the right of the Figure where they are ejected from the mould by a plunger r<1> pressing down a plate q<4> carrying pins which enter the holes of the mould. The ejector is operated by the movement of the cross-head n through levers s, r. A fixed blade serves to remove surplus glass from the top of the mould e as the table moves after the moulding operation. The plungers are mounted on springs as shown. A treadle c operating a clutch is provided to stop the machine when required.

Filed: 1940-09-06
Abstract: 545,013. Reciprocating pumps. WAHLMARK, G. A. Sept. 6, 1940, No. 13946. Convention date, Nov. 22, 1939. [Class 102 (i)] [Also in Groups XXIV and XXIX] In a multi-cylinder swashplate pump the swashplate is adjustably mounted to vary the quantity and/or direction of fluid discharge, the quantity adjustment being determined by an annular or cylindrical member against which the swashplate bears. In the form shown, plungers 25 are reciprocated in cylinders 24 by a wobble plate 26 pivoted at 28. The cylinders 24 are connected by ports 45 to a cylindrical chamber 40<SP>1</SP> which is connected by passages 46, 46<SP>1</SP> to fluid ports 32, 33, and which contains a wheel-like 'valve 34 driven by an eccentric 35 on driving shaft 21. The valve 34 is of the kind described in Specification 516,721, [Group XXIX], and serves to prevent flow between the ports 32, 33 except by displacement of the pump. The wobble plate 26 has a cylindrical bore 59 which is engaged by a spherical portion 58 on the arm 57 of a bar 55 which is slidable longitudinally in a keyway 56 in the driving shaft 21 and which has teeth 60 inter-engaging with teeth 61 on the inner race 54 of a ball bearing 53. The latter connects the bar 55 to a tubular cylinder 50 in a central bore 47 formed in the cylinder block 38 and containing a fixed piston 48. The movable cylinder 50 determines the direction of inclination of the wobble plate 26. The latter bears against a tubular cam control member 65 acting as a piston in a cylinder formed between the portions 36, 38 of the pump. The member 65 has a cam opening 67 which co-operates with rollers 70, and gear teeth 78 meshing with gear teeth 77 on a feed-control piston 75 reciprocated in a transverse cylinder 76 under the control of a screw stop 80. The member 65 is reciprocated for changing the stroke from zero to any one of a plurality of different short strokes, and is movable transversely to change to a full stroke. When cam member 65 engages the wobble plate 26 throughout its periphery, there is no stroke at all. This pump, and the circuit to which it is connected, are both kept full of fluid by means of a rotary make-up pump 90 comprising a toothed pinion 91 keyed on an extension 92 of the pump shaft 21 and meshing with a ring gear 93 provided with the usual segmental guard 94. The make-up pump draws fluid through inlet 95 and discharges it through outlet 96, passage 96<SP>1</SP> fitted with a relief valve 97, strainer 103 (not shown), and check valves 101, 102 in passages 99, 100 leading to the pump ports 32, 33. High pressure relief valves 104, 105 are provided in passages 106, 107 connected to the ports 32, 33. The make-up pump 90 supplies fluid to the pistons 48, 65 and 75, under the control of a cylindrical valve 108 which is movable into any one of five positions in a cylindrical bore 109 corresponding to " rapid right," " feed right," "stop," " feed left," and " rapid left " movement of the work support actuating piston 110.

Title: Improvements in and relating to polyethylene terephthalate films
Inventor: STEAD BRIAN DOUGLAS
IPC: B29C55/14
Filed: 1961-04-19
Abstract: Biaxially oriented polyethylene terephthalate film having a high tensile strength on the longitudinal direction is made from an unstretched amorphous polyethylene terephthalate film by first stretching it transversely to a stretch ratio in the range 2.65:1 to 3.2:1 and then longitudinally to a stretch ratio greater than 5.05:1 at a temperature above 120 DEG C. and at a rate of stretching of at least 5,000%/min.  Preferably the transverse stretch ratio does not exceed 3.0:1, transverse stretching being effected at about 80 DEG -100 DEG C. and longitudinal stretching at 120 DEG -160 DEG C.  The rate of stretching in the longitudinal direction is desirably less than 100,000%/min.  Partial shrinkage of the film may be permitted in the transverse direction during longitudinal stretching.  In this case, the transverse stretch first applied to the film may be at a stretch ratio greater than 3.2:1, provided that the shrinkage which takes place during longitudinal stretching brings down the overall transverse extension to 3.2:1 or less.  After stretching, the films may be heat-set in known manner while held at, e.g. 150 DEG -230 DEG C.  Films so made normally have a yield strength of 30,000 p.s.i. or greater, a tensile break strength of at least 35,000 p.s.i. with an elongation at break not above about 25% and in the transverse direction a yield strength of at least 8,000 p.s.i.  A voided film may be made by the use of a higher rate of transverse stretching. Specification 811,066 is referred to.
